— Prentiss in "The Last Word"
Emily Prentiss is the current Unit Chief of the BAU who first joined the team two episodes after Elle Greenaway resigned from the FBI for good. At the end of Season Seven, she resigned from the BAU and accepted a position with Interpol in London. She was replaced by Alex Blake, who held the position until her own departure at the end of Season Nine. The position was then taken over by Kate Callahan for the duration of Season Ten before her own departure. She rejoined the team in Season Twelve and was then promoted to Unit Chief following the resignation of Aaron Hotchner. For a time, she was placed on administrative leave and suspension, pending an investigation by Assistant Director Linda Barnes; her position taken over by Jennifer Jareau temporarily.
Emily Prentiss was born on October 12, 1970, at 7:12 a.m. Due to her mother's diplomatic background, Prentiss traveled a lot when she was a child, living in several Middle Eastern countries and at one point in Rome. In "Demonology", she reveals that she became pregnant as a teenager in Rome from wanting to fit in. When she went to talk to her priest, he said that if she got an abortion, she would not be welcome in the church. Her friend Matthew Benton encouraged her to go to an abortion clinic, and after the abortion, he helped her find the courage to come back to church. In "Tabula Rasa", Garcia reveals that Prentiss graduated from Garfield High School in 1989 and that she was a goth at the time.
In her first appearance, she recognizes Hotch from one of his first commands: security clearances for her mother, Elizabeth Prentiss, a U.S. diplomat. Her arrival surprises both Hotch and Gideon, as neither of them had signed off on the transfer. Prentiss insists her parents have not pulled strings for her. Ultimately, she joins the team at the end of "The Last Word" on a probationary basis as a replacement for Agent Elle Greenaway.
She is a graduate of Chesapeake Bay University, where she earned her B.A. in Criminal Justice ("Annihilator") and the University of Yale and has been working for the FBI for a little under ten years, primarily in the Midwest. Due to spending her early life with her parents on diplomatic missions to the Middle East, she speaks fluent Arabic and is familiar with that area's local culture. She also speaks fluent Spanish, French, Italian, and some Russian. She appears to be skilled at chess, and it is possible that she is better at the game than Reid. JJ once asked Prentiss how she could handle the stress from being with the BAU, especially since her last position was a desk job. Hotch concurred that she had "never blinked," and Prentiss could only reason that she "compartmentalizes better than most" ("Revelations"). After a bad date in the following episode, she admits to Morgan that she is a "nerd," despite how much she tries to hide it. For this reason, she hasn't had much success romantically. She discovers that she and Morgan share similar tastes in books when they begin discussing Kurt Vonnegut, particularly Slaughterhouse 5.
Prentiss is very level-headed and calm, sometimes it could be said that she seems to be dealing with the cases in an even more professional manner than some other members of the BAU. However, like Elle before her, Prentiss lets her own emotions get the better of her on a few occasions. She has been shown to react emotionally at the crime scenes and feels a strong surge of empathy for the victims. She also appears highly intelligent and driven. Prentiss is willing to put herself at risk to protect others and has a very sarcastic sense of humor.
On the Job in Season Two
In, "Sex, Birth, Death", Prentiss is accused by Hotch of leaking information about a case to a congresswoman. Firmly denying this accusation, Prentiss tells Hotch that she thinks politics "makes people distrustful, hate themselves, tear families apart and damage people," implying that her home life as a child was not pleasant, due to her mother's job.
At the end of "No Way Out II: The Evilution of Frank", BAU Section Chief Erin Strauss reveals to Prentiss that she arranged for her to join the BAU, contrary to Prentiss's belief that she was accepted on her own merit. Strauss asks Prentiss to sabotage Hotch's career by spying on him and relaying confidences back to Strauss, especially concerning Elle Greenaway's shooting of a suspect and Reid's struggle with Dilaudid. She seems to consider this offer, and the season ends with a cliffhanger.
In "Doubt", Prentiss is called by Strauss to see if she has made any process on finding information on Hotch. Prentiss throws her cell phone in the nearest trash can after hanging up.
In "In Name and Blood", Prentiss decides to resign from the FBI to avoid betraying Hotch. After some convincing from Hotch, she returns to the team for a case; her resignation having never gone through the system due to technical interference from Garcia, and the issue has not been brought up since. Upon her return, Section Chief Strauss remarks that neither Prentiss, Hotch, nor the rest of the team would be able to climb the ladder to the top because of all this, thus putting an end to some of Prentiss's future ambitions.
In "3rd Life", she implied to Hotch that when she was an adolescent, she smoked and dressed inappropriately as a way to rebel against her parents.
In "Tabula Rasa", a high school photo reveals that Emily was a goth.
In the episode "Minimal Loss", she and Reid are held hostage by a religious cult. When the cult leader finds out that one of them is an FBI agent, Prentiss admits her identity, partially to protect Reid, and ends up getting beaten by the leader. Prentiss antagonizes the leader by twice repeating "I can take it" to keep the rest of the team from coming in, knowing that they are listening via bugs and that it would put everyone inside of the building in danger. Later, Prentiss reassures Reid that it was not his fault and asks him not to feel guilty.
In "Demonology", more of Prentiss' childhood is revealed after hearing and learning from an old friend that their childhood friend died, prompting her and the rest of the team to investigate a series of deaths involving exorcisms.
In "Nameless, Faceless," Prentiss is the first to discover that Hotch is missing. She first tells Garcia and then Reid first but not before promising them not to tell the others working on their current case. She stays with him the entire time he's at the hospital after Foyet stabs him nine times, even when the rest of the team go to retrieve his ex-wife and son, Haley and Jack.
In "Outfoxed", Prentiss and Hotch visit Karl Arnold in prison to ask for his input on a current case; Prentiss even flirts to Karl to get more out of him. After the interrogation, Karl reveals that he has received communications from Foyet and that he is planning to return to make a final stand against Hotch. Karl reveals several notes featuring Foyet's signature symbol, The Eye of Providence.
In "100," Prentiss began tearing up as she heard Haley being shot three times by Foyet. She's shocked to see Hotch has beaten Foyet to death.
In "The Slave of Duty," Prentiss worried about Hotch before being called in. She became repeatedly disturbed by how the victims were forced to live their final moments in fear and insecurity by the unsub. She personally kicked him to the ground and as she puts her gun to his head, she tells him that when an inmate tries to have his way with him, just play along, as he forced his victims to do.
In "Retaliation", Prentiss is in a car accident while transporting a prisoner to the local police station. Despite sustaining severe injuries, Prentiss manages to escape the police cruiser via the windshield and fire on the fleeing suspects as they escape. Morgan finds Prentiss on the roadside and she is taken to the hospital where she is treated for a concussion and several cuts and contusions. She insists on quickly returning to the job and plays an instrumental role in solving the case.
In "The Fight", Prentiss is partnered with Mick Rawson, a member of the BAU's Red Cell team while on a case; during which they playfully flirt with each other. She is almost killed by the unsub but Rawson, who was using a sniper rifle from another rooftop, manages to shot the unsub twice and kills him.
In "Exit Wounds", Prentiss is debating on whether she should call Rawson or get a cat. She eventually gets a black cat named Sergio.
In "Compromising Positions", she risks her life and is nearly killed while going undercover in order to dissuade a mentally-unstable unsub who is in the company of numerous bar patrons and employees, all in danger of being gunned down. When she accidentally gets one of the unsub's facts wrong, he is provoked into shooting her, but she shoots him first, firing her pistol hidden in a purse. Prentiss then watches as he dies.
In "The Thirteenth Step", Prentiss learns from a former colleague at Interpol, Sean McAllister, that Ian Doyle, an apparently highly dangerous criminal, has escaped from his North Korean prison and gone off the grid and apparently killed a man and stole his car. Sean warned her that he might come after her and that everyone is in danger.
At the beginning of "Sense Memory", in her apartment, when the phone rings and the caller ID is unknown, Prentiss lets it go to message and listens to the recording. The caller, presumably Doyle, is completely silent and hangs up. In response, Prentiss sets up some noise-traps near all entrances and exits in the apartment, sits down in the hallway with a gun, turns off the lights, and waits.
When Prentiss returns to her apartment after a case, she finds a package by her door. When she opens the package, it turns out to contain a small, purple-white flower. There is a flashback to some time earlier when she is working in a flowerbed filled with the same flowers, apparently by a mansion somewhere in France. When authorities, presumably Interpol, arrive and drive away with her, Doyle watches her from a balcony. He calls someone and tells the other person to "stay on on top of [it]". As he is arrested by English-speaking authorities, he looks down at one of the flowers that Prentiss dropped.
In "Coda", Doyle resurfaced in D.C., confronting Prentiss and warning her that he will seek revenge on her soon before leaving. Soon after in "Valhalla", he began killing people connected to his case as well as their families. During the investigation, he kills one of Prentiss's former colleagues, Tsia Mosely. It is also revealed that Prentiss, Sean, Tsia, and two other colleagues were part of a team assembled by Interpol that profiled terrorists and helped apprehend them, codenamed JTF-12.
In "Lauren", Prentiss goes after him alone. As she attacks him and his men near The Black Shamrock, a bar in Boston at which he and Prentiss (as "Lauren Reynolds") first met. As she holds a submachine gun at his men, he flanks her and shoots her in the abdomen. She survives, wearing a bulletproof vest, and is abducted and taken to the group's HQ. She is tortured and beaten as Doyle recounts what happened after his arrest: he was taken to a prison in North Korea, where he resisted in interrogation for two years, hoping to see his son, Declan, again. When he was shown a series of pictures of Declan and his legal guardian being executed by a mostly unseen figure, he broke down completely and would remain there for another five years. Unbeknownst to him, the pictures were actually staged by Prentiss in order to save Declan from his father's life. The BAU , having found the photos, notices that the nails of the hand holding the gun are completely bitten down; Prentiss was a compulsive nail biter when nervous. Obtaining the address of the house, they conduct a stealth raid on it, killing all of Doyle's men. As Doyle, furious to learn how he was deceived by Prentiss, begins furiously beating her. She gets the upper hand and knocks him to the floor with a wooden stick. Once she drops it, Doyle grabs it and stabs it into her abdomen. Hearing the gunfire approach, he escapes and isn't seen for the rest of the episode. The BAU arrive and take Prentiss to a hospital, where they are told that she didn't survive. They all attend Prentiss' funeral. Her headstone is marked "Fidelity, Bravery, Integrity", the motto of the FBI. In the final scene, JJ is seen approaching a woman (whose face is unseen) in France and giving her passports for three different countries and a bank account in each one. The woman's hands are shown to the viewers to have completely bitten-down nails, implying that it is Prentiss, who is alive and has faked her own death in order to go into hiding from Doyle, thus protecting the rest of the BAU team from him. The rest of the team missed her dearly and struggled to cope with the loss for the remainder of the season.
In "It Takes a Village", she reunites with the team when they are forced to team up with Doyle in an effort to save Declan from a trio of international criminals seeking revenge on Doyle. Although they are successful in saving Declan, Doyle is shot and mortally wounded by the trio's leader, dying as Prentiss watches in shock.
In "Proof", Prentiss and JJ received the cold shoulder from Reid because he was not informed that she was still alive after Doyle supposedly "killed" her, viewing that as betrayal. She eventually made amends with Reid, telling him that she regretted every moment of not letting him know but that it was necessary in order to protect herself and more importantly, the team. She reminds him that while he lost one friend, she lost six. Reid forgave her and they became friends again.
In "Dorado Falls", Morgan lies to Prentiss and tells her she had to undertake recertification training. When she confronted near the episode's end, he told her that he didn't want to lose her again and needed some reassurance. They agreed to ten hours of training.
In "Unknown Subject", Prentiss started to deal with her traumatic experience caused by Doyle. This is particularly evidenced by her personal connection with Regina Lampert, a victim of a serial rapist whom she later abducts, tortures, and tries to kill in revenge.
In "A Thin Line", Prentiss and Morgan have disagreements about an FBI training session. Prentiss is shot in the arm by the unsub before being shot down by Morgan. She is temporarily injured and forced to wear a sling. Morgan feels guilty that Prentiss was again hurt on his watch and tries to apologize to Prentiss. After gently teasing him, Prentiss tells Morgan that what happened to her was not his fault, it was just part of the job.
In "Divining Rod", Prentiss places a sealed bid on a house in the upscale DuPont Circle neighborhood of Washington, D.C. When her bid is accepted, Prentiss seems reluctant to go forward with the purchase.
At the beginning of "Hit", Morgan joins Prentiss on an inspection of the DuPont Circle house. She shares with Morgan her doubts about going through with purchasing a home. When the team is called in to work a bank robbery and hostage situation, Clyde Easter contacts Prentiss to help identify one of the robbers, an international criminal. Clyde also offers her a position at Interpol, as chief of the London office. She appears to consider the offer.
In "Run", Prentiss risks her life to defuse a bomb attached to William LaMontagne, Jr. At JJ and Will's wedding, Prentiss confesses to Morgan that she is unable to feel comfortable in her old life after her near-death encounter with Doyle and subsequent period of hiding. She admits that she is strongly considering Clyde's job offer. At JJ's reception, Prentiss is shown looking mournfully at the rest of the team before joining each of them to dance. It is implied that she will leave the team and accepted the job at Interpol.
In the Season Eight premiere "The Silencer", Morgan and Garcia come back from England, where Morgan was on temporary duty, after visiting Prentiss. They say she has settled in nicely.
She is possibly referenced in "Magnificent Light", when Morgan and Garcia discuss about a friend of the former's, who comes from England, and Garcia makes a comment that "[they] like England, remember?"
Prentiss was mentioned in "To Bear Witness", when Garcia reveals that she had to ask her for assistance in finding any potential past victims of an unsub who performs lobotomy on his victims; this led to the discovery of a victim in Berlin, Germany.
In "X", it is revealed that after Blake's departure from the BAU, Hotch had tried reenlisting Prentiss to the position, but she declined; her reason, according to Rossi, she just doesn't want to come back.
Prentiss reappears in "Tribute", when she enlists the help of the BAU in catching an international copycat serial killer. She had become personally involved in the case since 2015, when the unsub began killing London prostitutes in an emulation of Jack the Ripper; her efforts to apprehend him failed and resulted in the death of an undercover police officer, Detective Inspector Louise Hulland. It is revealed that she has been in a relationship with a man named Mark for some time. She is also having recurring nightmares about Louise's death, which she had personally witnessed. Prentiss eventually gets closure in the case when she and the rest of the BAU corner the unsub, who she shoots and kills.
When Hotch had to leave on temporary assignment in "Taboo", Prentiss volunteered to rejoin the BAU during his absence.
A few weeks later, during "Elliott's Pond", it is revealed that Hotch, in reality, had resigned from the FBI and gone into witness protection with his son Jack to avoid escaped serial killer by proxy Peter Lewis, who had been actively stalking Jack. He had also named Prentiss his successor as BAU Unit Chief.
Picking up from the ending of "Red Light", in "Wheels Up", Prentiss and the team is involved in a deadly car crash caused by Scratch and as a result, is drugged, abducted, and tortured by him for Hotch and Jack's location. She is rescued by Alvez and Reid.
In "Killer App", Prentiss talks to Alvez about his last encounter with Scratch on the roof.
In "Miasma", Barnes questions Prentiss' leadership and brings up several events; from Reid's false imprisonment, to the Roswell, New Mexico case and Stephen Walker's death at the hands on Scratch. Prentiss calls Barnes out on the true nature of the review: Barnes wants to be the next FBI Director and is on a power trip. When Barnes wants Prentiss to give up either Reid or Rossi, if not both of them, she refuses; "standing by her team and the actions they've taken." Barnes not only suspends Prentiss from indefinite active duty, but will be personally overseeing the BAU as part of her investigation.
In "Annihilator", Reid visits Prentiss at her apartment, who's preparing to leave the team again and had back to Interpol when Reid talks her out of it, remaining her of the people she and the team saved over the years. It is revealed that Prentiss deleted the recorded conversation she and Reid had when he was arrested in Mexico. After the team returns to the bullpen after completing a case, Barnes reinstalls Prentiss but will be reassigned.
In "Last Gasp", Prentiss has been reassigned to an OPR unit within the FBI and dislikes her partner for his obnoxious behavior and odd body odor. The team gathers at her apartment for a case that Barnes did not approve. Nevertheless, the team manages to save the latest victim, who happens to be the daughter of a prominent senator, who makes Barnes reinstate Prentiss as Unit Chief and gives Prentiss hiring authority after being told of JJ's termination. Prentiss and the team reunite and celebrate after Barnes is told to keep her hands off the BAU.
In "Innocence", Prentiss is worried about Garcia, especially after seeing her broken unicorn mug in the trash. Garcia admits to Prentiss that she's still struggling with being abducted and her recently strained relationship with Carlos after forgiving the man who killed their parents. Prentiss glues the mug back together and she and Rossi bring Carlos in to help Garcia cope as well as better their relationship.
In "Flesh and Blood" they have their first date. The date is in her apartment and when Andrew arrives, he finds Emily cooking and with comfortable clothes. The cooking doesn't result, so they order a pizza. The evening is interrupted by a case. When the case is over, she asks Andrew for breakfast in her apartment. Although she has cooked to prove she's not a terrible cook, they kiss and leave the food for later.
In "Rusty", Prentiss is now maintaining a long-distance relationship with Mendoza. They have struggled with the relationship, but Andrew wants to make it work while Emily keeps creating barriers between them. In the end, he is having dinner with his daughter Keely and Emily shows up in his place. They make amends and Keely and Emily first meet.
In "Face Off", in the aftermath of Everett Lynch killing his mother, Roberta and six SWAT agents, Barbour tells Prentiss in her office that her name has been withdrawn from the FBI Director shortlist, but is still the BAU's Unit Chief.
In "And in the End..." Prentiss and Mendoza are looking for a house in Denver though she's still keep her D.C. apartment for comfort.
